Considering the Boston rhymesayer’s first and to date only Booth feature, the highly-acclaimed Don’t Wanna Hear It, arrived on our front page almost exactly a year ago, you shouldn’t feel too bad if the name Reject doesn’t ring any bells. And if it does, that’s a damn fine memory you’ve got there—want to count cards for me on my next trip to Vegas? Either way, a listen to new promo single Go to Sleep should be just the thing to wake you up to the Boston representative’s uniquely dope brand of underground fire. Vherbal handles production duties, flipping Sons of Champlin’s psychedelic funk opus You Can Fly into a melodically gritty backdrop for mind-expanding bars from the headliner and a few equally venturesome homies.

Garden State newcomer MaddMaxx brings up the rear, drawing on Greek mythology in an inspired closing 16.
